Abstract: VEHICLE SUPPORTED WINCH                     A B S T R A C T         The invention is concerned with an improvement in a vehicle supported winch which comprises a supported rotatable drum for receiving a cable.  Such a winch further includes means for selectively transmitting rotary motion to the drum having a normally disengaged input clutch, a normally engaged brake for stopping rotation of the transmitting means and a normally disengaged disconnect clutch and wherein the application of fluid pressure drivingly engages normally disengaged members and drivingly disengages normally engaged members.  The winch further includes a source of pressurized fluid.  Also part of the winch are means communicating with the fluid source and each of the input clutch, the brake and the disconnect clutch for selectively controlling application of fluid pressure thereto. The communicating means provide a BraKe-On position at which the input clutch, the brake and the disconnect clutch are not pressurized, a Reel-In position at which only the input clutch is pressurized and a Brake-Off position at which only the brake is pressurized.  The improvement of the invention comprises using as the fluid source a pump in combination with an accumulator communicating therewith for stoning fluid pressure produced by the pump when it functions and for supplying fluid pressure when functioning of the pump is retarded.  Usually in accordance with the invention, the pump is driven by a transmission of the vehicle and functioning of the pump is retarded as the transmission stalls.

Abstract: ABSTRACT           A three-phase rectifier circuit is connected to provide a d-c output voltage as a function of the three-phase energy passed to the rectifier circuit.  This energy is reduced in amplitude over a voltage divider circuit and passed through an optically-coupled detector circuit to provide a control signal indicating the presence of energy on all phase conductors of the supply line.  If a fuse blows in one line, or if the power on that line is interrupted for any reason, the ripple content of the rectified voltage increases.  This is sensed by a detector circuit to energize an alarm and/or interrupt the main power bus to the load.

Abstract: A TRAY FOR SHIPMENT OF FROZEN ITEMS                 Abstract of the Disclosure A tray for the shipment of frozen items such as frozen pies which is stackable within a box with other identical trays so that each individual frozen item is prevented from contact with any other frozen item. The tray has a bottom from which four sides extend outwardly and upwardly. The sides comprise a longitudinal pair of sides and a lateral pair of sides. A plurality of projections extend upwardly along the center line between the longitudinal sides, and two rows of protuberances, one row located on each side of the plurality of projections, extend upwardly. The plurality of projec-tions forms a divided partition. Each protuberance is formed by a long slope which extends upwardly from the bottom of the tray towards one lateral side of the tray and by a short slope which ex-tends almost vertically downwardly from the upper end of the long slope to the bottom of the tray. Thus, each protuberance has a resulting inverted "L" shape along its longitudinal cross-section.          The long slopes of all the protuberances are orientated toward the same lateral side. Each frozen item is prevented from contact with another frozen item by the protuberances and the divided partition. The frozen items which are adjacent a long slope lie along the long slope, and thus assume an inclined position with respect to the flat bottom of the tray.

Abstract: MULTIPOINT POLLING TECHNIQUE          Abstract of the Disclosure A multipoint polling system wherein a multipoint switch selectively connects a plurality of remote terminals to a central station in response to remote terminal addresses transmitted on a signaling path to the multipoint switch.  Polling apparatus stores portions of a remote terminal address list provided by the central station and transmits individual ones of the stored remote terminal addresses on to the signaling path.  The polling apparatus periodically requests different portions of the remote terminal address list and replaces the stored remote terminal address portion with the requested remote terminal address portion.         The multipoint switch is advantageously comprised of a plurality of sections with each section of the switch responsive to a portion of the address list for establishing a signaling path between the central station and selected ones of the remote terminals defined by the address list portions.  The failure of a multipoint switch section to respond to remote terminal addresses results in the address list portion normally transmitted to the failed section and the address list portion normally transmitted to a remaining active section being transmitted to the active section whereby the active section polls the remote terminals previously polled by both the failed and active sections.

Abstract: Abstract of the Disclosure Speed capability of a rotary stepping motor of the harmonic drive type is markedly increased by providing a stiffer, i.e. harder to radially deflect, structure of its rotor. Elimination of magnetically permeable bridging material as heretofore employed is made possible also in an alternate construction. Basically, thickness of a flexrotor or flexspline wall is made greater than hitherto relative to its outside diameter to provide a stiffness insuring efficient operation at increased natural or resonant frequency. Higher capability of the thicker-stiffer flexspline to maintain its sinusoidal shape during operation results in less tooth wear and increased efficiency over a longer operating life. When concentric ring bridging is incorporated, its total wall-to-outside-diameter ratio thickness is advantageously substantially that of the novel flexrotor or flexspline itself to obtain higher step rates efficiently.
